Battery Types
Batteries come in different sizes, types, amp-hour capacity,
voltages and chemistries. Here are a few guidelines that will
help in battery selection, and ensure that the batteries are
properly maintained. The best source of the most appropriate
settings for the C-Series will be from the manufacturer or
supplier of the batteries.
Automotive Batteries
Automotive and truck batteries are designed for high
cranking power – not deep-cycling. Do not use them unless
no other battery type is available. They simply will not last
long in a cycling application.
Maintenance-Free Batteries
This type of battery is often sold as a RV or marine battery,
but is rarely appropriate for use with a PV system. They
typically have an additional reserve of electrolyte, but are
vented. This is not the same as a sealed battery.
Deep-Cycle Batteries
Best suited for use with PV systems, this type of battery is
designed to be more deeply discharged before being
recharged. Deep-cycle batteries are available in many sizes
and types. The most common is the vented liquid electrolyte
battery.
WARNING: Explosion/Corrosion Hazard
Batteries can vent hydrogen-sulfide gas, which is corrosive to
electronic equipment. Batteries also generate hydrogen and oxygen
gas that can explode when exposed to a spark. Be sure to read the
safety precautions on page viii regarding batteries.
